How to use authentication provided by repoze.who/what in TurboGears2.1?

[Cosmia Luna]

I'm new to TurboGears and switched from Django before, though Django works well.

In a nutshell, how to get a User instance by email and password like Django does, and log he/she in?

How does repoze processing to check if a user is logged in or not? How can I tell repoze how to determine identified or not? And how to log a user in?

Of course I can manually check the database, manually set the cookies and session ... but I think it's a better way to use the repoze, maybe. 

I read many documentations ( including the repoze.who/what's documentation, of course ), and get a lot of not-very-useful-by-now knowledge, but don't know how to do that.

I use TurboGears 2.1

Thanks

What you are looking for is probably:

response.headers =
request.environ['repoze.who.plugins']['main_identifier'].remember(request.environ,
{'repoze.who.userid':user_name})

The user_name variable is the User.user_name field in a standard TG2
configuration.

For a more structured function to use take a look at
